block: Reset buffer alignment on detach

BlockDriverState member buffer_alignment is initially 512.  The device
model may set them, with bdrv_set_buffer_alignment().  If the device
model gets detached (hot unplug), the device's alignment is left
behind.  Only okay because device hot unplug automatically destroys
the BlockDriverState.  But that's a questionable feature, best not to
rely on it.
